URP-PSX

URP-PSX

Playstation 1 era retro graphics plugin optimized for Unity's Universal Rendering Pipeline with Shadergraph. The aim of this plugin was to use Unity's new pipeline to create NPR (non-photorealistic) PSX-style retro graphics with the shadergraph as the basis for materials and URP's render features as the basis for post processing effects.

Features

The plugin comes fully-featured with a single lit/unlit graph where you can enable/disable features according to your needs (and even modify them). I segmented every feature into a subgraph to hopefully make it easier to just plug n' play.

Shadergraph:

• Lit/Unlit shader variants
• Specular Lit variant
• Camera-based vertex clipping
• Vertex snapping/Jittering
• Texture Pixelation for crushing texture resolution
• Color Precision for lower or higher color Fidelity

URP Render Features:

• Screen-space fog
• Screen-space pixelation/color precision adjustments
• Screen-space dithering

Note: Make sure you set the render features in the pipeline asset

Compatibility

Unity 2019.3.7f1 Universal Rendering Pipeline/Shadergraph (7.1.8)

Known Issues

• Unity's Shadergraph still has a long way to go when it comes to creating NPR effects. You might experience some lighting clipping issues if you are using the PBR master node. To fix it, I tweaked some settings in the URP pipeline asset settings so they are barely noticeable.

Support

I developed this plugin out of passion/nostalgia for retro ps1-style horror games. But, if you found this plugin useful and want to show your support, consider sharing it,buying me a ko-fi.
